Using a large set of trading accounts, we study the determinants of retail investing in passive Exchange Traded Funds (P-ETFs). Controlling for investor characteristics related to their risk-return profile, trading activity, and socio-demographics, we show that the probability and magnitude of...

We link a seemingly biased trading behavior to equilibrium asset prices. U.S. equity mutual fund managers tend to sell both their big winners and big losers. This selling pressure pushes down current prices and leads to higher future returns; aggregating across funds, we nd that securities for...

We theoretically show that there is a fundamental disconnect between the disposition effect, i.e., investors’ tendency to sell winning assets too early and losing assets too late, and its common empirical measure, namely a positive difference between the proportion of gains and losses...

Measuring mutual fund managers’ skills by Microsoft’s TrueSkill algorithm, we find highly skilled managers to behave self-confident resulting in higher risk-taking in the second half of the year compared to less skilled managers. Introducing the TrueSkill algorithm, which is widely used in...

Despite the ability to explain many puzzling phenomena in financial markets, direct tests of reference-dependent preferences of Kahneman and Tversky (1979, 1992) have mainly been conducted in experimental settings. We propose a novel test based on revealed preferences of real-world investors....

We examine whether professional money managers overreact to large climatic disasters. We find that managers within a major disaster region underweight disaster zone stocks to a much greater degree than distant managers and that this aversion to disaster zone stocks is related to a salience bias...

Using mutual fund flow, we empirically test whether choices made by investors are consistent with preferences implied by prospect theory. Our findings support this hypothesis. When allocating capital to mutual funds, investors evaluate funds based on the past performance distribution and choose...

We investigate the portfolio performance of retail investors who combine stocks and passive exchange traded funds (P-ETFs) by relying on both proprietary trading records and survey data. We use propensity score matching to control for all the key investor characteristics and better identify the...

Recordkeepers in DC pension plans are often paid indirectly in the form of revenue sharing from third-party funds on the menu. We show that these arrangements affect the investment menu of 401(k) plans. Revenue-sharing funds are more likely to be added to the menu and are less likely to be...

Using detailed mutual fund holdings in the US market, we estimate active mutual fund managers’ loss aversion as a function of both funds’ past performance and asset allocations. We document a substantial variation in loss aversion over time. We further find managers' loss aversion is higher...
